HENRY DICKINSON, OF FLUSl-IING, NEIV YORK.

BOTTLE-CLOSURE.

Specification of Letters Patent.

Patented Sept. 5, 1905.

Application filed April 5,1904. Renewed February 18, 1905. Serial No. 246,339.

To all whom, it may concern:

Be it known that I, HENRY DICKINSON, a citizen of the United States, residing at Flushing, in the county of Queens and State of New York, have invented a new and useful Improvement in Bottle-Closures, of which the following is a specification.

My present invention pertains to a combination of a bottle with a stopper, the latter being operatable by means of a toggle-joint, the levers composing said toggle-joint being bifurcated and the ends of one of said levers being .fulcrumed in the material of which the neck of the bottle is composed; and the object of my present invention is to provide such a conformation of the material which surrounds the fulcra of the toggle-joint-operating lever that the latter, and by means thereof the entire stopping device, may be easily detached from or attached to the bottle, and I obtain said improvement without necessitating any diminution of the bearing-surfaces of the fulcra of the operating-lever.

l have illustrated my improved bottle-closure in connection with a bottle of the ordinary beer-bottle shape.

In the drawings accompanying this specification, Figure I is a front elevation of the neck portion of a bottle made in accordance with and equipped with the stopper device of my present invention. Fig. 2 is a side elevation of same, and Fig. 3 is a vertical section through the center from side to side.

Referring to the drawings, a bottle 2 is provided with a thickened portion 1 about the mouth 3 thereof, which thickened portion is formed with depressions L 4. opening outwardly from similar positions upon opposite sides of the bottle-neck. It is not necessary that the thickened portion 1 should extend entirely around the neck of the bottle, as its function in my improved device is to present material about the depressions l; but as the adopted form of bottle has a thickened portion about the month, which in a measure insures against chipping of the month, my thickened portion 1 if made entirely surrounding the mouth of the bottle will perform the dual function of preventing breakage and presenting material for pivoting a member 5, which may be described as follows: A piece of heavy spring-wire or iron capable of a slight bending and a spring back into place is bent into a U, the diameter of which U is approximately that of the neck of the bail-like lever 5. The material forming the bail-like lever 5 at the ends of the U-shaped embracing portion is bent in three-quarters of a circle to form eyes 6 6 and thence across the ends of the U at approximately right angles thereto, the two ends projecting parallelly for some distance and then turned in toward and into alinement with one another.

The ends of the bail-like lever 5 are sprung apartsutiiciently to allow of their being passed about the thickened portion 1 of the bottle and allowed to spring into the depressions 4 4., when the bail-like lever 5 will be securely pivoted upon the neck of the bottle for use in practically the same way as the lever, which is now pivoted upon a ring secured about the neck of the bottle. The glass or other nonmetallic material forming the walls of the depressions a Ti: forms a smooth bearing for the lever 5 and will not rust up.

A stopper is carried by a bail 7, which is provided with bent-in and alined ends, which ends are sprung into and pivoted in the eyes 6 (3 of the bail-like lever 5.

I prefer to make the thickened portion 1 of the bottle about the depressions a a thicker at the upper sides of said depressions than at the lower sides thereof, so that the pivot ends of the baillike lever 5 will have a large bearing-surface upon the upper sides of said depressions and there will be a great thickness of material at those points to lend strength as the pull upon the stopper-bail is brought to bear upon those points when the bail-like lever 5 is pressed.

In a bottle which is formed according to my invention the material below the fulcra of the operating-lever is so formed as to project but slightly from the bottoms of the depressions in which the operating-lever is fulcrumed, thence extending in oppositely-disposed curves downwardly and outwardly to the general surface of the bottle.

It is obvious that various changes may be made in the details of construction of this device without departing from the spirit of my invention.

\Vhat I claim, and desire to secure by Letters Patent, is

The combination with a bottle of a stopper which is operatable by means of a togglejoint, the operating-lever of said toggle-joint being bifurcated and fulcrumed in the material of which the neck of the bottle is composed; the material of which the neck of the bottle, to form the embracing portion of a bottle is composed being so formed below the slightly from the bottoms of the depressions fulcm of the operating-lever as to project but i to this application in the presence of tWo sub.-

scribing Witnesses. 1n which the operatmg-lever 1s fulcrumed,

thence extending in oppositely -disposed HENRY DICKINSON v curves, downwardly and outwardly to the Witnesses:

general surface of the bottle. FREDA SCHULTZ,

In testimony whereof I have signed my name LILLIAN PERRY.
